Peeling/cracking layer on the touchscreen

When I bought the car, there was what looked like a small chip or crack on the radio screen. I thought the previous owner had probably dropped something on it and that was what caused it. However, I’ve noticed that it’s getting bigger and bigger over time.

I’ve also noticed quite a few other people having the same problem. Does anyone know why this happens? Is there any way to stop it from spreading? What is the layer that is actually peeling/cracking? I was thinking about maybe peeling the whole thing off, but I don’t think that’s really possible.

The only option is to replace it with a new one, or else you have to live with it.
